Clarifying Questions (5 mins)

• Looking at the product context, I'm thinking Gloo Edge might be facing scalability challenges as its user base grows. Could you provide more information on the current scale of operations and the specific performance issues we're seeing?

Why it matters: Helps determine if we need to focus on horizontal scaling, vertical scaling, or optimizing existing resources. Expected answer: Handling 100,000 requests per second with occasional latency spikes during peak hours. Impact on approach: Would prioritize solutions that address sudden traffic surges and optimize request handling.

• Considering user behavior, I'm curious about the types of APIs being managed through Gloo Edge. Are we dealing primarily with microservices, monolithic applications, or a mix? What's the average payload size and complexity of these API calls?

Why it matters: Influences optimization strategies for different API types and payload sizes. Expected answer: Primarily microservices with a mix of small to medium-sized payloads. Impact on approach: Would focus on microservices-specific optimizations and efficient payload handling.

• From a product lifecycle perspective, where does Gloo Edge stand in terms of feature completeness versus performance optimization? Are we looking to add new capabilities or primarily enhance existing ones?

Why it matters: Determines if we should focus on refining current features or introducing new performance-enhancing capabilities. Expected answer: Core features are in place, now focusing on performance enhancements. Impact on approach: Would prioritize optimizing existing features over adding new ones.

• Regarding external factors, how does Gloo Edge's performance compare to competitors in high-traffic scenarios? Are there specific benchmarks or customer feedback driving this improvement initiative?

Why it matters: Helps set performance targets and identify areas where we can differentiate. Expected answer: Performance is competitive but lagging in certain high-concurrency scenarios. Impact on approach: Would focus on improving concurrency handling and response times.
